DISCUSSION

(This Afternoon Through Wednesday) Issued at 1049 AM MST Thu Feb 5 2026

Western NOAM ridge will shift east, supporting mild weather for the region. The ridge does breakdown next week as zonal semi- active flow returns with some chances for precip. Very mild weather air in place today with near 100 percent sunshine and record highs in parts of the area. Frontside impulse will skirt along the eastern side of the ridge and support a backdoor cool front into the region late tonight, with some low clouds and patchy fog possible across far NW SD to central SD. The front will stall out over the region Friday, with mild conds to the west and cooler conds to the east, bust still mild for early Feb. Warm air will spread back east for Sat and Sun, warmest Sunday when a few low 70s are expected once again on the Plains east of the BH. Cool front will move through the region Monday with breezy winds and some chances for rain or snow Monday night through mid week as a series of impulses traverse the flow. Although it will be cooler, it will remain seasonally mild next week with highs in the 30s and 40s after Monday.
